All latest information shall follow, since this is the same project, just the latest progression.
The good old Austin Rover Mini with its antiquated A Series engine which has its roots back in the 1950's where long stroke engines were favoured as a result of taxes imposed on cylinder size.
Would anyone believe the A series engine would be so durable and yeild such power figures as they do these days? Well, here's how it's done, or, here's how I have done it at least, and note, this is a conservative build, there is room for improvement.
The car
Stripped back to bare metal and repainted
The Engine
A BMW K1100 16v Twin cam cylinder hear mated to a Rover A+ Series engine and transmission with a SAAB 93/95 Garrett GT1752 turbocharger. Engine is 1293cc and compression 8.5:1, I could have gone much higher but the combination of parts gave me this without going positive deck with the pistons. That said, I know I can throw 30psi at this and it'll still work, que the Garrett GT2056............. a future project haha.

I've custom wired the engine loom and checked functionality of all sensors and actuators. Just waiting on the plenum completion and final plumbing before the initial start
It's starting to get tight for space in there now!
